[SM} Excellent, hope this plays out as we wish for.

[SM] Cool, if I might ask what fraction of the sync are you setting the
traffic shaper for and are you doing fine grained overhead accounting (or
simply fold that into a grand "de-rating"-factor)?

[SM] Yes, although IIUC they are reporting the interquartile mean for
the two loaded latency estimates, which is pretty conservative and only really
"triggers" for massive consistently elevated latency; so I expect this to be
great for detecting really bad cases, but I fear it is too conservative and
will make a number of problematic links look OK. But hey, even that is leaps
and bounds better than the old only idle latency report.

[SM] Inside the EU the challenge is to get national regulators and the
BEREC to start bothering about latency-under-load at all, "some mainstream
publicity" would probably help here as well.
